Description

Die Erfindung betrifft eine Empfangsantenne nach dem Ober­ begriff des Patentanspruchs 1.The invention relates to a receiving antenna according to the upper Concept of claim 1.

Die Empfangsantenne findet Verwendung beim Empfang von Sa­ tellitensignalen, z. B. zur Navigation, sowie in Land-, Wasser- und Luftfahrzeugen.The receiving antenna is used when receiving Sa tellite signals, e.g. B. for navigation, as well as in land, Water and air vehicles.

Für derartige Empfangsantennen eignen sich Schlitzantennen mit Strahlungsfeldankopplung, die z. B. eine Speiseleitung auf der Rückseite eines Substrates besitzen (B. D. M. Pozar, IEEE Trans. Antennas Prop. Vol. AP-34, No. 12. S. 1439-1446 (1986)). Slot antennas are suitable for such receiving antennas with radiation field coupling, the z. B. a feed line on the back of a substrate (B. D. M. Pozar, IEEE Trans. Antennas Prop. Vol. AP-34, No. 12. pp. 1439-1446 (1986)).  

Aus der japanischen Patentanmeldung 0 628 923A ist eine Schlitzantenne mit einem aus einem dielektrischen Material gebildeten Hohlraum bekannt, deren Schlitz in eine lei­ tende Wand gebracht ist.From Japanese patent application 0 628 923A is one Slot antenna with one made of a dielectric material formed cavity known, the slot in a lei end wall is brought.

Aufgabe der Erfindung ist es eine Empfangsantenne anzuge­ ben, die eine optimale Impedanzanpassung und minimales Rauschen gewährleistet, sowie einfach an die Fahrzeugka­ rosserie anpaßbar ist.The object of the invention is to provide a receiving antenna ben, the optimal impedance matching and minimal Noise guaranteed, as well as easy to the vehicle box body is customizable.

Die Aufgabe wird gelöst durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale. Vorteilhafte Ausgestaltungen und/oder Weiterbildungen sind den Unteran­ sprüchen zu entnehmen.The task is solved by the in the characterizing part of claim 1 specified features. Beneficial Refinements and / or further training are the Unteran to take sayings.

Die Erfindung hat den Vorteil, daß durch den integrierten um- und abschaltbaren rauscharmen Vorverstärker (LNA) her­ vorragende Empfangsleistungen erzielt werden. Mit der An­ tenne sind durch den um- und abschaltbaren LNA sowohl zir­ kular als auch linear polarisierte Wellen zu empfangen. Weiterhin ist die flache, mechanisch robuste Ausgestaltung der Antenne, sowie deren unsichtbare und aerodynamisch op­ timale Anordnung in der Fahrzeugkarosserie vorteilhaft.The invention has the advantage that the integrated switchable and switchable low noise preamplifier (LNA) excellent reception performance can be achieved. With the An tenne are both zir receive both polar and linear polarized waves. Furthermore, the flat, mechanically robust design the antenna, as well as its invisible and aerodynamically op timing arrangement in the vehicle body advantageous.

Die Erfindung wird im folgenden anhand eines Ausführungs­ beispiels beschrieben unter Bezugnahme auf schematische Zeichnungen.The invention is based on an embodiment described for example with reference to schematic Drawings.

Gemäß Fig. 1 ist die Antenne 1 als schlitzförmig Ausspa­ rung in die metallische Fahrzeugkarosserie 2 eingebracht. Um die rückseitige Abstrahlung zu verhindern, ist die An­ tenne von hinten durch einen Hohlraum 3 mit geringer Tiefe abgeschlossen. Der Hohlraum ist mit einem Dielektrikum ge­ füllt, z. B. Teflon, Polystyrol o.a. Der rauscharme Vor­ verstärker (LNA) ist durch unterschiedlich lange Zuleitun­ gen L₁, L₂ mit der Antenne verbunden, so daß z. B. beim Empfang von zirkular polarisierten Wellen, die Addition der beiden um 90° gedrehten linearen Polarisationszustände im LNA erfolgt. Die richtige Phasenlage der Wellen wird über unterschiedlich lange Zuleitungen L₁, L₂ eingestellt. Der LNA ist in das Dielektrikum eingebracht und über Zu­ leitungen L₁, L₂ mit der metallischen Karosserie verbun­ den. Die gesamte in die metallische Karosserie einge­ brachte Antenne ist mit einer Lackschicht 4 beschichtbar.Referring to FIG. 1, the antenna 1 is provided as a slit-shaped Ausspa tion introduced into the metallic car body 2. To prevent radiation from the rear, the antenna is closed from behind by a cavity 3 with a shallow depth. The cavity is filled with a dielectric, e.g. B. Teflon, polystyrene or the like The low-noise pre-amplifier (LNA) is connected by different lengths of supply lines L₁, L₂ to the antenna, so that, for. B. when receiving circularly polarized waves, the addition of the two 90 ° rotated linear polarization states in the LNA. The correct phase position of the waves is set via leads L 1, L 2 of different lengths. The LNA is introduced into the dielectric and connected to lines L₁, L₂ with the metallic body. The entire antenna brought into the metallic body can be coated with a lacquer layer 4 .

Die Stromversorgung und die Auskopplung des verstärkten Signals erfolgt z. B. über die im Dielektrikum eingebrach­ ten Leitungen L₁, L₂. Für die Leitungen L₁, L₂ können Microstrip-Leitungen verwendet werden. Dies hat den Vor­ teil, daß der Aufbau der Antenne in Sandwich-Technik mög­ lich ist. Die Verwendung von Koaxialleitungen bietet den Vorteil, daß geringere elektrische Verluste auftreten.The power supply and the decoupling of the amplified Signal takes place z. B. over the broken in the dielectric ten lines L₁, L₂. For the lines L₁, L₂ can Microstrip lines are used. This has the intent partly that the construction of the antenna in sandwich technology is possible is. The use of coaxial lines offers the The advantage that lower electrical losses occur.

Die schlitzförmige Antennenkontur kann als linearer Schlitz, Ringschlitz oder konusförmiger Schlitz ausgestal­ tet sind.The slot-shaped antenna contour can be linear Slot, ring slot or conical slot are.

In Fig. 2 ist z. B. eine Ausgestaltung eines Ringschlitzes 5 dargestellt. Der rückseitige Hohlraum hat eine Tiefe von z. B. 1 mm. Die Zuleitungen L₁, L₂ sind z. B. Microstrip-Lei­ tungen mit einer Länge von L₁=λ4/ und L₂=λ/ bei einer Wellenlänge von z. B. λ=18,75 cm (entspricht einer Frequenz f=1,6 GHz. In Fig. 2 z. B. an embodiment of an annular slot 5 is shown. The back cavity has a depth of z. B. 1 mm. The leads L₁, L₂ are z. B. Microstrip lines with a length of L₁ = λ4 / and L₂ = λ / at a wavelength of z. B. λ = 18.75 cm (corresponds to a frequency f = 1.6 GHz.

Die Querschnittsfläche des Hohlraums der Antenne wird je nach Form der Schlitzantenne gestaltet, da die Form die Resonanzfrequenz der Antenne bestimmt.The cross-sectional area of the cavity of the antenna is each designed according to the shape of the slot antenna, since the shape of the Resonance frequency of the antenna determined.

Alle Bauteile werden bündig zur Oberfläche der metalli­ schen Fahrzeugkarosserie ausgeführt. Damit kann die An­ tenne überlackiert werden und ist somit nicht sichtbar. Da für die Schlitzantenne die gesamte sie umgebende Metall­ fläche (z. B. das gesamte Fahrzeugdach) als Massefläche wirkt, wird eine nahezu halbkugelförmig isotrope Richtcharakteristik erreicht, wie sie für die geplanten Anwendungsgebiete notwendig ist. Durch Integration der An­ tennenstruktur in eine konvexe Oberfläche (Fahrzeugaußen­ haut) kann eine nierenförmige Antennencharakteristik er­ reicht werden.All components become flush with the surface of the metalli the vehicle body. This allows the An over-lacquered and is therefore not visible. There for the slot antenna all the metal surrounding it area (e.g. the entire vehicle roof) as a ground area acts, is an almost hemispherical isotropic Directional characteristics achieved as for the planned Areas of application is necessary. By integrating the An structure in a convex surface (vehicle exterior skin) can have a kidney-shaped antenna characteristic be enough.
